It took 19 years to drill 12,262 meters deep. The crust is 30 miles or 50 kilometers deep.Doing the math:12,262 meters/19 years = 645.37 meters/year50 km = 50,000 meters50,000 meters/645.47 meters/year = 77.47 yearsThis is assuming technology remains at the current level of mining and drilling.
Some people un-familiar with caves or possibly a person advertising a cave will claim a pit is "bottomless." Usually you can't see the bottom of these pits, so their story is convincing. Also, they may throw a rock into the pit, it lands in soft dirt and doesn't make a sound, so some gullible people will believe them. The answer to the question is that most of these pits are not even a 30 meters deep. A person should not enter these pits without proper training on techniques for climbing long free-hanging ropes. There are thousands of caves where the pit could be 100 meter free-fall. and there are plenty more deeper than that. The Velebita Pit in Croatia is the deepest pit inside of a cave at 513 meters deep. You would be far safer rappelling off of a sky-scraper, than exploring a deep pit without training or the proper equipment.
a canyon
as coal is made of pplant remains that have been buried long ago,it is so deep inside earth.
None, All the dirt has been removed from the hole.

None. It's a HOLE.

What is the answer for rounding 14389 to the nearest thousands
Well there's hardly any earth in a hole... if you do it properly. Trick question out of the way, if the hole was filled in, it would take 150m3 of dirt
a lot of dirt.
If it's a hole, there would be no dirt in it, right?
No dirt because its a hole
You cannot answer this question mathematically as you do not know the length of the hole, if it is a square hole (i.e. 1m long) then there was 3m3 of dirt.However if it is a lateral thinking question then the answer is none. It is a hole, therefore it is empty
none, it is a hole
None. Its a hole
